Bishop's Cap, Organ Mountains, New Mexico Plant Fossils Unknown

They do have a strong similarity with horn corals from the Ordovician in Cincinnati and N. Kentucky. -
Went out for a couple of hours, and need help!

And as far as I understand it, "Series" is the Chronostratigraphic unit (strata) and "Epoch" is the Geochronologic unit (time). The ICS places both as alternates at the same spot in their chart. ChronostratChart2023-06.pdf- 8 replies

It keeps the same shine also, in sunlight and shadow, nothing changes. It also has no straight or cubed looking edges like the pyrite I've seen seems to have. Pyrite is also highly magnetic isn't it? No part of this thing is magnetic even slightly.
-
I agree with both posts above. What are the second set of photos in the first post? Chert in limestone is my guess as well. NOt a skull.

I agree with blastoids for #9. Don

I would like to add that I was given an incorrect weight for this "ball". I weighed it and it is 16.42 ounces. I will get measurements as soon as I can.

One quick way to tell gold from pyrite is to put this thing in sunshine. The gold/pyrite will shine nicely. Now turn around and put it in your own shadow. Gold will shine nicely some more but pyrite will be dull yellow in the shade.

Excellent work. You have real talent.

I had thought it might have been some sort of cannon ball as well. It's not very soft at all. I know gold is soft and the "c' looks and feels like it could be gold, the a few pieces that I can see look like actual rocks but the rest seems to be a nonmagnetic metal. It has me stumped. I can not figure it out. I've never seen anything like it.

Found Hiking is it just a weird rock or skull
DPS Ammonite replied to lasvegasxj's topic in Fossil ID
Looks like chert in limestone. See if the reddish and gray areas are scratched with a metal knife blade. See if both rock types fizz in pool acid. If the gray rock is ground up you can use vinegar to see if it fizzes. You may need a hand lens to see.

Nor me, I'm afraid.

Hi, Could you please place the Isle of Skye in the world for foreigners ? Thank you. coco

I'm a little confused. Is this all the same rock in all of the photos, the first ones at the outcrop and the last ones indoors? I'm not seeing a skull at any rate.
-
Is that list visible in this forum? I have seen two kind of dyrosaurid teeth around and would be curious to know more accurate id.

Found this hiking a mountain in the desert outside Las Vegas. Is it just me or is it an actual skull fossil. Its way to clean obviously shaped. Even with the darker sediment where an eye socket would be. Im not a fossil hunter so this may just be a neat rock but heres the pics. Any help is appreciated

Hi and welcome to the forum. I can not help with the ID, but I think it could be helpful if you could tell (and maybe show) some examples of specimens you already Identified for context. Best Regards, J

Sorry, I'm not seeing foot prints either.
-
Looks like weathering patterns, see semi circle shape on left hand side also, so not footprints in my opinion.
-
These evenly spaced imprints from right to left smaller to bigger sure look like clawed foot imprints. Any guesses? Found on Delaware shore.

Below is the tooth of a dyrosaurid, some of which you may recognise from this thread here. I was originally under the impression that dyrosaurid teeth, like many crocodile teeth, were (unfortunately) non-diagnostic, but it appears that @Anomotodon was able to compile a list of dyrosaurid crocodiles known from the phosphates of the Ouled Abdoun Basin, and the morphology of their teeth, so I wondered if it might be possible to identify mine. Given the fact that my tooth has two carinae, and "medial/lingual curvature with a convex labial" (@pachy-pleuro-whatnot-odon's word, not mine) and no striations, I personally believe this tooth to be that of a Chenanisuchus, but I'm no expert on the matter. Thanks in advance for any guidance Othniel

That Great White has gorgeous coloration!
-
Pholad borings does seem quite possible for the larger shapes. The more bubble-like texture would present these bivalves with an opportunity for easy digs. In general, similar shapes that don't appear to be tracks tend to bring the track hypothesis into question.
-
This one might be hard to identify more specifically as the preservation is not the greatest and it does not appear to be complete.
